Only what endures.
A watch designed to be inherited is, by its nature, a sustainable object. We take the rest of the process just as seriously.
Responsibly sourced metals
All gold and platinum used in our ateliers is certified through the Responsible Jewellery Council chain of custody, tracing each ounce back to its mine.
A watch built to be repaired
Every caliber is designed to be serviced, not replaced. Spare parts for house movements remain in production for a minimum of thirty years.
Packaging that decomposes
Our boxes are FSC-certified wood and undyed cotton — no plastic film, no laminated foam, nothing that outlives the watch inside it.
Chosen for a hundred years, not for this season.
